DIVIDED MOLD.

Application filed March 14, 1921.

Y '0 a] Z w from it m my concern Be it known that l, Enwnnn J. Renae a citizen of the Jnited States, residing at Chicago, in the county oil? Cook and State of Illinois. have invented certain new and useful Improvements in Divided Molds. of which the following is a specification.

This invention relates to molds tor casting objects which are to be released by the opening of the mold. and has for its purpose to provide an improved construction of mold which will be of simple and light construction. convenient to manipulate. etlicient in rapidly producing articles which involve the use of two or more connected cavities, one of whi h is offset from the other tor the purpose o'l producing an appendage or pro jection on the casting and adapted to produce the body oi the casting and its appendage in different relative positions in different castings.

Theinvcntion proceeds upon the principle of dividing the mold into members located on opposite sides of a main dividing plane. hose separation will open one cavity of the mold. subdividing the member on one side of said main divided plane by a plane which intersects (preferably perpendicularly) the main dividing plane. and also intersects the additional cavity the cavity first named having within it a coring member or the like which is adjustable in order to enable the body of the casting to be formed in differentpositions relatively to its appendage that is formed in the aforesaid additional cavity.

ln the accompanying drawings the preferred embodiment of the invention is shown by way of illustration,

Figures 1 and 2 being, respectively, a plan View and a section on the line 2* 2* of Figure 1 showing a mold adapted for cash inga pillar plate strap for storage batteries;

*igures 3 and 4 being, respectively. a section oi Figure 1 on the main dividing plane and a section of Figure 3 on the line 4"-4 of Figure 3: and

Figure 5 being a specimen of the work produced by the mold shown in Figures 1 to 4.

The base member 11 is located. on one side of the main plane of separation m. to. while the complementary members 12. 12 are located on the other side of said plane and hinged thereto through the medium of the pintle 17. The primary cavity 13 is formed in the member 12 with its bottom wall sup- SErial No. 452310.

plied by the face 13 of the member 11, and the additional cavity 1 .1 communicating therewith is formed partly in one and partly in the other ot the two complementary members 12, 12. The gate 1:) of. the mold is the upper end of the additional cavity H. and the means For arresting the mold members in proper registry with the base member con sists of the screw 16. in this instance inserted through the base member into the member 12, and holding the member 12 normally stationary with reference to the base so that only the member 12 need be moved upon the pintle 17 to empty the mold. In the cavity 13 is a coring member 21 which adapts the mold to produce the pillar plate strap 20 ot a battery (Figure 5) the shank Q0 of which is produced by the additional cavity 1-L-l. Core member 21 is adjustably secured in the cavity 13 by means ot' the sc ews 22 working in the longitudinal slots 23, and in this way may be adjusted longitudinally to bring the ribs and recesses of the castings in different positions relatively to the shank 20. so that the strap will be adapted to serve as a righthand strap or a left-hand strap in the battery, as may be desired. Preferably the ends 24 of the strap forming core constitutes the ends of the cavity 13.

The members of the mold may be held together by handles 18 and 19 during the process of pouring and in otherwise manipulating the mold.

I claim:

1. A mold comprising members on opposite sides of a main dividing plane and constructed with a cavity that is opened by the separation of said members; the portion of the mold lying on one side oi said main dividing plans being constructed with an additional cavity which communicates with the cavity first named and being subdivided by a plane intersecting said additional cavity and said main dividing plane; said mold having within its first-named cavity a coring member adapted to form a reticulated 0r 'grated structure with openings definitely redetermine the form cast in said cavity, and an additional cavity in said mold communicating with the cavity containing said c0r ing' member and adapted to form a shank on the casting; said coring member being; adapted to slide longitudinally in the cavitywhich contains it to modify the relation of the grating to the shank.

3. A divided mold comprising relatively movable members constructed with la cavity opened by their separation, a grating" core carried by one of said members in p. r, ion

to determine the form cast in said cavity, and

an additional cavity in said mold. communicating with the cavity containing said coring member and adaptedto form a shank on the casting; said coring member being adapted to slide longitudinally in the cavity whichcontains it to modify the relation'of adapted to slide longitudinally in the cavity which contains itto modify the relation oi the grating t0 the shank; and said mold having means for adjustably locking said coring member in place.

5. A divided mold comprising relatively movable members con structed with a cavity opened by their separation, a grating core carried by one of said members in position to determine the form cast in said cavity, and an'additional cavity in said mold communicatino with the cavity containing said coringnici'nber and adanted to form a shank on the casting; said coring member being adapted to slide longitndinally in the cavity which contains it to modity the relation of the grating to theshank; and said coring member constituting end closures of'the cavity in which it is located and slot and screw connections between the mold body and the ends of said coring mem ber.

6. -A divided mold; comprisingrelatively movable membersconstructed to form a grid cavity and a post cavity communicating therewith. and a grid core located in the grid cavity and having means forholding it in different positions therein to vary the relation of the post formed in the post cavity to the grid produced by the grid cavity.
